Hi all,

What is the difference between polynomial and rational coordinate stretching types? And also, what is the best PML thickness for a start? Could you please tell me a rule of thumb for PML parameters (such as thickness, scaling factor, scaling curvature parameter) for a start?

Many thanks!

Hi,

Is there a possiblity to apply absorbtion boundary condition for a plate excited with sinusoidal to avoid end boundary refleciton? I am using a time dependent solver and I am propagating lamb waves?

Could anyone have solution to it?
